MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 368,083, dated August 9, 1887.

Application filed September 9, 1886. Serial No. 213,112.

To all whom it may concern.-

Be it known that I, ROBERT EMIL FELneEs, a subject of the King of Prussia, residing at New York, in the county and State of New York, have invented new and useful Improvements in Mechanical. Movements, of which the following is a specification. I A

The object of this invention is to provide a mechanical movement capable of delicate ad- I j ustment and ofaccurate working; and I accomdriving-pawl.

plish this object by means of the device set forth in the following specification and claims, and illustrated in the accompanying drawings, in which Figure 1 isa side elevation of my mechanical movement. Fig. 2 is a section in the plane 00 as, Fig. 1. r

Similar letters indicate corresponding parts.

A is a frame, of iron, wood, or other suitable material. In this frame is suitably mounted a shaft or aXle,B,on which turns a ratchet-wheel, G. The ratchet-wheel'Cis actuated or turned in the direction of arrow 9 by a driving arm or lever, D, swinging on the'shaft B. A drivingpawl, E, is hinged or suitably attached to the arm D. A spring, .15, is attached to the arm D and holds the driving-pawl in engage;

ment with the ratchet-wheel. The ratchetwheel 0 is provided with teeth, a portion of said teeth being indicated in the drawings by the numbers 1 to 8.

The driving-pawl E is provided with teeth a b c d, adapted to engage with the teeth on the ratchet-wheel C. The pawl-teeth a b c d are arranged in suitable ways or guides in the The driving-pawl is pressed upon by a spring, F, and springs a are applied to force said teeth a I) c d into engagement with the .teeth of the ratchet-wheel O. The pawl-teeth a b c d are fractionally or differentially arranged in relation to the ratchet-wheel teeth-that is, for example, as shown in the drawings. When the pawl-tooth a is in engagement with the driving-gear tooth 1, a move- V ment of the driving-pawl E in the direction (No model.)

1 ratchet-wheel teeth one pawl-tooth will always be brought into engagement with a ratchetwheel tooth, and the driving-pawl will actuate the ratchet-wheel even if the oscillations of the driving-pawl should be through a less or smaller distance than thelength of one of the ratchet-wheel teeth. If desired, the driving-pawl E can thus be made to impart a slow motion to the ratchet-wheel.

A stop-pawl, G, is hinged or suitably attached to the frame A, and prevents retrograde motion of the ratchetwvheel. A spring, H, presses upon the stop-pawl G, and the lat ter is provided with sliding pawlteeth e f g-h, acted on by springs a The stop-pawl teeth 6 fg'h are also fraction-ally or differentially arranged in regard to the ratchet-wheel teeth, as already explained in relation to the driv ing-pawl teeth, so that, for example, as shown in the drawings, the stop-pawl tooth e, being in engagement with the ratchet-wheel tooth 5,

one of the stop-pawl teeth f g It will be brought less or smaller distance than the length of aratchet-wheel tooth. The oscillations of the driving-arm D and driving-pawl E about the axle or shaft B impart motion to the ratchetwheel 0.

To limit or regulate the oscillations of the driving-arm D, I provide a regulator, I. This regulator I consists of a suitable surface, either plane or curved, with which the driving-arm comes into contact, thereby arresting or stopping the motion of the driving-arm in one direction. In the example shown in the drawings the regulator consists of a plane hinged at J to a base or support, L, said plane being held in an inclined position by an upright or arm, K. By providing the arm K with a 2 ceaoae screw-thread and with nuts i 7; the inclination of the plane or surface can be varied and adjusted as desired. The base or support L of the regulator I is adapted to slide or travel in a suitable guide or way, M, in the floor or in a base-plate of the mechanism.

When the lower part of the regulator I is in proximity to the arm D, the arm D is free to oscillate through a considerable space and to impart considerable movement to the ratchet-wheel. As the regulator is moved to bring the higher part of the regulator I to the arm I), the motion of the arm D, and consequently of the ratchet-wheel O, is diminished. The regulator I thus enables the motion of the ratehct-whecl C to be adjusted or controlled as desired. To soften the contact between the arm or lever D and the regulator I, a cushion or pad, j, of suitable soft or elastic materialsuch as leather-may be applied to the arm D.

In the example shown in the drawings the regulator I is automatically actuated. The ratchetwheel G has connected to it a gear, 'N, and by a train of gears, O I Q R S, motion is imparted to the shaft or axle 121, connected to the gear S. An arm or pawl, T, is connected to the shaft an, and every revolution of the pawl T revolves the gear-wheel 'U a certain distance in the direction of arrow 10. To the axis of the gear-wheel 'U is attached a bevel geanwheel, \V, gearing into a bevel gcar' wheel, X. As the gear U is revolved in the direction of arrow 10 the bevel wheel X and its shaft Y and the gear-wheel Z are re volved in the direction of arrow 11. The gear wheel Z is connected to the shaft Y,or mounted on said shaft, and said gear-wheel Z engages with a gear-wheel, p, which in turn engages with a rack, Z, on the regulator. As the gear 1) is revolved in the direction of arrow 12 the regulator is moved in the direction of arrow 13, bringing the higher part of the regulator into proximity with the arm D and gradually diminishing the movements of the arm or levcr D and of the ratchet-wheel.

The gears O I Q R S U are suitably mounted in the frame of the device, and the shaft Y and gear are suitably mounted or supported on the floor or base of the device. A stoppawl,V, suitably pivoted or mounted,prevents retrograde motion of the gear U. To return the regulator I to its startingpoint, it is only necessary to disengage the stop-pawl V from the gear U, when the regulator I can be moved by hand to the position desired; or by connecting the gear U with a weight or spring, 0, which is wound up by the revolution of the gearU, said spring or weight, upon the disengagement of the stop-pawl V, will automatically return the regulator Itoits starting-point. In the drawings I have indicated a coiled spring, 0, one end of which is attached to the frame of the device and the otherend to the axle of the gear U.

In the drawings the driving arm or lever D is shown as being actuated bya cord or chain, q, to which cord or chain a suitable oscillating motion is imparted. The cord or chain q is connected to a hook or eye, 1', on the drivingarm D. Said hook or eye 1' can be adjusted or moved to various positions along the driving-arm I) by a screw, 8, actuated by a fingerbutton, t, and when the proper position of the hook or eye 1* has been ascertained the revolution of the screw 8 can be stopped by a setscrew, it. Said screw 3 engages a nut, r, of the book 1*. The action of the cord or chain (1 on the drivingarm D can thus be adjusted or regulated.

I have found it advantageous to supply means for lengthening or shortening the cord In the drawings is shown an eye or hook, c, engaging the hook or eye r. The eye 0'' is provided with a frame or guide, it, having a recess for a linger-button, f. The finger-button f is tapped for the passage of a screwshanlt, 8, having a hook or eye, ii, to which the cord or chain q is attached. A proper motion of the finger-button f will cause the screw-shank e to be moved so as to secure the proper relation of the cord (1 to the driving arm D.

In the drawings I have shown an example of my mechanical movement applied to a loom, the letter in indicating an oscillating arm as, for example, the batten of a loom-to which the cord q is attached, and fromwhich batten the cord receives motion as said batten oscillates. This motion of the cord q oscillates the driving-lever D and revolves the train of gears. The shaft in of the gear S serves as the take-up or cloth-beam, on which the woven or finished cloth or fabric from the shed a a is wound. As more cloth is wound on the cloth beam or shaft m, the diameter of the roll of cloth becomes greater, and if the cloth-beam m revolved continually at the same speed the circumference of the cloth-roll, as said roll increases,would acquire greater speed but since by my mechanical device the regulator I gradually diminishes the action or throw of the lever D, the circumferential speed of the cloth beam or shaft in is diminished as the diameter of the cloth-roll is increased, so that by a proper adjustment and construction of the parts the cloth-roll can always be caused to turn at a fixed circumferential speed, thus avoiding any breakage or injury in the operation of weaving.

Of course I do not confine myself to the application of my mechanical movement to a loom, butI mention a loom as a mechanism in which my movement can be advantageously employed. I can, for example, also employ my movement in such apparatus as papermills, in case it is desired to roll up finished paper at a uniform speed.

The arm or pawl T is adjustably connected. to or mounted on the shaft m, and can be fixed in position by a set-screw, n. Said pawl T can thus be adjusted to properly engage with the gear U. If it is desired to stop the motion of the gear U, and consequently of the regulator I, it is only necessary to slide or IIS move the arm T into such a position that no engagement of the arm or pawl T and of the gearU takes place. The gear-U and the bevelgears W X, with the shaft Y, constitute an actuating mechanism for the regulator I, and by connecting said actuating mechanism to the ratchet-Wheel G, as shown in the drawings, said actuating mechanism receives motion only as the ratchet-wheel is actuated.
